Unfortunately, the 1/72 Italeri kit is it. There was an old Revell kit in 1/48th, but the molds were destroyed in an accident and it hasn't been seen since the early '80s. Any surviving kits are collectors items and can go for quite a bit.
The Italeri 1/72 one can come out quite nicely though. It just needs a little work. You can see a fine example of how it can come out here.
Good luck.
